BLOW-OUT PATCH."

Application illed June 20, 1927. semi in. 200,149.

The object of this invention is to provide a tire patch which may be readily and effectively applied and held in place. The invention consists of a patch piece provided with an adhesive attaching strip having self-adhering wings, which are capable ofbeing stuck together and then folded over and stuck to the patch piece, as I will proceed now more fully to explain and final- 1y claim.

In the accompanying drawings illustrating the invention,.in the several figures of which like parts are similarly designated, Figure 1 is a perspective view with the patch is open. Fig. 2 is a perspective view with the 'wings united by a double fold. Fig. 3 is a. similar view with the wings'united by a single fold.

The patch iece 1 may be of any appropriate materiail and size, of substantially the form and proportion shown in Fig. 1. The inner side or face of this patch piece is made or inert material or provided with an inert substance so as not to adhere to the body which'it surrounds, but the outer face is provided with an adhesive or tacky substance so that the patch piece when applied will adhere to the casing or'shoe. To this piece is attached the strip 2, of strong material, such as canvas or duck, coated or saturated with an adhesive or tacky substance in such way that such substance appears on both sides of the material. The strip 2 is of greater length than the width 3 or circumference of the patch piece 1, so as to provide wings 3 standing off .from the adjacent edges of the piece 1.

When the patch piece 1 is applied in use, it is secured in place firmly by means of the strip 2' having its wings brought togetherlo' and caused to adhere by means of their tacky:

surfaces, and then this joint may be further].

secured by folding over-u on themselves the" thus adhered wings, eac fold separately adhering and the final told turned over and adhered to the body of the stri 3 as shown in Fig. 2. vBut, as shown in ig. 3,the' adhered wings may be folded over in a single fold and then caused to adhere to the i no body of the strip. f

'The strip 2 thus provides a. self-adheri g and self-locking member forthe patch piece,"-

and consequently the patch piece may. be

refldil'y applied.
